I used block_design and passed it a item_parameters with column item that was the integers from 1:nrow(item_parameters) this caused a very difficult to read error.
Error in rep(0, (max(block_len) - length(block_items))) :
invalid 'times' argument
There are many possible fixes for this. for my purposes, it worked to just overwrite item to be 1:nrow(item_parameters), but doing that would cause issues if you expected to know the item column outside of block_design, so I made a fork that instead just gives a helpful error an exists.
Minimal working example:
param <- NAEPirtparams::parameters
item_par <- param[param$level %in% 8 & param$subject %in% "Mathematics" & param$year %in% 2015, ]
item_par$item <- sample(1:1e5, nrow(item_par))
item_par <- item_par[1:32,]
# this gives the error I share above about invalid `times` argument
block <- lsasim::block_design(n_blocks = 10, item_parameters = item_par)
My proposed version makes this error
devtools::install_github("pdbailey0/lsasim")
param <- NAEPirtparams::parameters
item_par <- param[param$level %in% 8 & param$subject %in% "Mathematics" & param$year %in% 2015, ]
item_par$item <- sample(1:1e5, nrow(item_par))
item_par <- item_par[1:32,]
block <- lsasim::block_design(n_blocks = 10, item_parameters = item_par)
# Error in lsasim::block_design(n_blocks = 10, item_parameters = item_par) :
# the item_parameters argument must have a column named item that contains the integers from one to the number of rows in item_parameters
I think fixed my bug with
item_par$item <- 1:32
# now it runs fine
block <- lsasim::block_design(n_blocks = 10, item_parameters = item_par)
If you like this, I'll propose a pull request for you to review.
